I have been planning on using a Mazda rotary engine for my project. I have researched the issues associated and decided to proceed along this path. Originally I planned on using a 1.3L, twin rotor turbocharged engine with a planned take off output of 200hp, Cruise HP of 150 and use the turbocharger to normalize up to 13000'. My goals include a cruise of approximately 175 MPH at altitude. I have already purchased an engine and planned on a rebuild. I have secured a planetary based PSRU built specifically for the rotary engine and was not looking to begin work on the engine program until after the flying surfaces had been built.
Well....while looking on one of the mail lists I follow, I saw a gentleman selling a Mazda 20b 3 rotor engine. This particular one was turbocharged, and came with a brand new IvoProp controllable propeller, a Marcotte 2.4:1 PSRU and many other assorted parts. The asking price was $4,000 for the lot. I pulled the trigger, made the deal, and drove out to Austin, Texas to pick it up. This will require a rethink on what my goals are as this engine should make approximately 240 HP naturally aspirated. I will certainly use all of it during takeoff, and then be able to use 200 HP during cruise up to 13,000'. I will need to ensure my radiator as well as my support structure is up to the task, but I think I got a steal! Pictures to follow.
